Then this is expected behavior: selecting a new font from that menu

I think that's what you asked for, by that "-3-" part in the font
spec. That's way too small.

But that doesn't cover future frames, either. It only affects the
existing GUI frames, per the doc string (and the code, which see).

I don't see how you deduce that. The text is very simple:
By default, Emacs displays text on graphical displays using a 12-point
monospace font. There are several different ways to specify a
* Click on `Set Default Font' in the `Options' menu. To save this
for future sessions, click on `Save Options' in the `Options' menu.
Unless you are saying that saving the options doesn't make this font
the default in future sessions, I see nothing wrong or misleading with
this text (except that the default font is not 12-point, not for many
years; I will fix that).
> It likens the behavior of `Set Default Font' to modifying
No, it doesn't mention default-frame-alist at all.
